What to do if the metallic feeling and white brightness of water-based aluminum paste are poor

With the coating industry's increasing demand for water-based aluminum pastes, the market's requirements for water-based aluminum pastes are also rising. Especially the metallicity, white brightness, hiding power and stability are the most important factors considered by customers. Several difficult factors in the promotion process. So, what should I do if the metallic feeling and white brightness of the water-based aluminum paste are poor?

The water-based aluminum paste itself will affect the metallic feel, white brightness, hiding power and stability, which are mainly manifested in:

1. The metal feel is not strong

There are several main reasons for this. On the one hand, the coating process of the water-based aluminum paste itself causes the metal feel of the water-based aluminum paste to become weak; the resin system selected by the customer is incompatible with the water-based aluminum paste, resulting in poor alignment. This will affect the final metallic feel; there is also a defect in the customer's own formula design that makes the metallic feel unable to come out;

2. The white brightness is not enough

Because the water-based aluminum paste itself is divided into two types, the green phase and the white phase, if you need a good whiteness effect, you need to find a white-phase water-based aluminum paste. Of course, the quality of the arrangement will also affect the effect of the final water-based aluminum paste. In addition, some customers who have high requirements for whiteness can also try to use fine silver;

3. Poor stability

The most prominent phenomenon is flatulence, which is also the most common problem encountered at this stage. On the one hand, the main cause of flatulence is that the coating layer of the water-based aluminum paste is not dense enough, or the temperature of the storage environment is caused. On the other hand, in the process of formula design, other raw materials added are incompatible with water-based aluminum paste, which is also the main factor causing flatulence problems.

The above content is to analyze the reasons for the poor effect of water-based aluminum paste.

The water-based aluminum paste is easy to disperse, good hiding power, concentrated and uniform particle size distribution, smooth and delicate surface, pure and bright color, strong metallic feeling and white brightness, and has good oxidation resistance and abrasion resistance. Heat resistance to acid and alkali. Therefore, it is used in products that require high environmental protection, such as clothing, paper printing, wallpaper, plastics and other industries.
